Introduction: Apraxia of eyelid opening (AEO) refers to impaired voluntary eyelid elevation of supranuclear origin. AEO is well-described in neurodegenerative disorders, but its frequency in stroke is unknown.
A 69 year-old right-handed man suffered from an infarct in the left anterior cerebral territory's artery, involving the anterior and middle parts of the corpus callosum, and the cingulum. He had a right crural hemiparesis with a grasp reflex of the right hand, and ipsilaterally a melokinetic and a
A 74-year-old right-handed woman without cognitive impairment suddenly developed nonfluent aphasia. Brain MRI showed acute infarction in the right frontal lobe and insula without involvement of the corpus callosum. A neurological examination demonstrated not only transcortical motor aphasia, but
Apraxia of eyelid opening is the incapacity of voluntarily eyelid opening in the absence of motor dysfunction or blepharospasm. It has mostly been described in extrapyramidal diseases and only very rarely in cortical lesions. We report a right-handed patient with a right frontal infarction
We report a pathologically documented case of infarction of the dominant thalamus with extensive involvement of the ventral lateral, ventral posterolateral, and lateral posterior nuclei and some involvement of the pulvinar. This patient exhibited linguistic impairment with features fairly typical
A 68-year-old right-handed woman showed "apraxia of eyelid opening" during an acute phase of hemorrhagic infarction in the right middle cerebral artery distribution. She showed paradoxical contraction of the bilateral orbicularis oculi muscles both against our order to open her eyes and even against
Limb-kinetic apraxia (LKA) is defined as an execution disorder of movements, resulting from injury of the corticofugal tract (CFT) from the secondary motor area. Diagnosis of LKA is difficult because it is made by clinical observation of movements. In this study, using diffusion tensor tractography
We report a 52-year-old right-handed man with cerebral infarction of the right anterior cerebral artery area. The MRI findings showed cerebral infarction in the trunk of the right corpus callosum, although some part of the posterior half of the trunk was spared. Some part of right precuneal gyrus,
We report on a patient with ideomotor apraxia (IMA) and limb-kinetic apraxia (LKA) following cerebral infarct, which demonstrated neural tract injuries by diffusion tensor tractography (DTT). A 67-year-old male was diagnosed as cerebral infarct in the left frontal cortex (anterior portion of the
Apraxia of eyelid opening is the inability to voluntarily open the eyes in the absence of motor dysfunction or blepharospasm. It has been described mostly in association with extrapyramidal diseases and only rarely in cortical lesions. We report a right-handed woman with a right subcortical lesion
Crossed aphasia refers to language disturbance due to right-hemisphere lesions in right-handed individuals, while magnetic apraxia is described as 'forced grasping and groping' caused by lesions in the contralateral frontal lobe. This is a case report of a 70-year-old right handed woman who suffered
BACKGROUND
Crossed apraxia is an unusual alteration in praxic function due to a cerebral lesion which is contralateral to that which would be expected. We report a case of crossed apraxia due to a right parietal lesion in a left handed patient who had been obliged to be right handed. We discuss the
We report a case of bilateral thalamic infarct associated with bilateral eyelid apraxia. This extremely rare condition provides us with an opportunity to map clinical and neuroimaging findings to help better understand brain function.
We reported a 50-year-old female patient with left supplementary motor area infarction who presented right lower limb apraxia and investigated the possible causes using transcranial magnetic stimulation. The patient was able to walk and climb stairs spontaneously without any assistance at 3 weeks
Ocular motor apraxia has been reported in bilateral frontoparietal lesions. We report a case of ocular motor apraxia after bilateral striatal infarctions. The patient had impaired voluntary saccades and smooth pursuits in the vertical and horizontal planes with an intact vestibulo-ocular reflex.
